To all whom it 'may concern:

Be it known'thatl, ERNST GEORG BERN- 'gas retorts with a mixture ofcoarse and fine coal in such 'a manner as to dispose the coarse coal ina continuous layer adjacent to and in contactalong its entire length,with a continuous layer of fine coal. The object of this arrangement isto secure a uniform evolution of gas inasmuch as distillation proceedsmore rapidly in the layer of coarse coal and the gases produced in thefine coalcan escape transversely'into the adjacent layer of coarse coal,where the large intcrstices afford an ample outlet for the gas.

My present application is a division of one filed by me in the UnitedStates Patent f Ollcc on June 19th, 1907, Serial No. 379,700.

The accompanying drawing illustrates in` yertical section an apparatusembodying my invention.r .l

From thc distant receptacle a` containing a mixture of coal of differentsizes, the material is transferred in the ordinary way into a hopper carl). This car having been brought to the proper position, coal isdischarged therefrom into a. receiver d vlocated `at a levelab'ove theupright retorts c contained'in an ovenor 'furnace r. By means of apartition e. the receiver d. is divided into two separate chambersf andg, one of which for instance f, is designed to receive the coarse coalwhile the other chamber, g, receives the fineco-al. In order toaccomplish the separation or grading of the coal an inclined sieve h. isprovided in the upper ortion ofthe receiver d., so that thecoal fa ingfrom the hopper car b. will be sorted automatically, the coarse coalrolling or sliding down the sieve into the chamber f. while the finecoalpasses through the sieve into the chamber g. Atits lower endthereceiver d, which is stationary, is rovided with adjacent outlets fromthe ciambers and g, whichoutlets are adapted to be c osed by valvesc'.Below the receiver d I provide, according to the presentinvention,one'or more distributing or` charging tunnels '1a.

mounted to travel on rails 7c. and divided by a partition a, into twocompartments, o and p arranged in re istry with the chambers f and grespective y of the receiver d. Each of the said com artments has itsindividual outletcoiitrolle by a slide q, the two outlets of each funnelbeing in registry with. one of the sets of retorts c. To feed thedifferent sets of retorts, some of the funnels fm.. may be bent to theleft and others 4to the right. The capacit f of each funnel m. will be acharge for t ie retort.

The operation is therefore as follows; -the `mixture of coal passes fromthe` container a and the hopper car b into the receiver d, where bymeans of the. sieve 7iy it is sorted into two grades separatelycontained in the respective chambersf and g, then by a proper 4manipulation `of the Slide valve i the proper amount of coal forafsinglc charging of one of the retorts will -bc transferred to thefunnel m. The two grades of coal will be kept separate, the upper end ofthe artition n being in the same plane with the lower end ofthepartition e. Then after bringing the funnel m. with its outletvertically above one of the retorts c. the slide q is pulled open toallow the two sizes of coal to pass out simultaneously while stillremaining separate, that is, without becoming mixed. Thus the retortwill contain the two grades or sizes of coal in separate layers orcolumns, the coarse coal being shown aslforming a column at the left andthe fine coalan equally high column at 'the right. Vi'hcn the furnace isheated the gas distilled from the tine coal will pass transversely intothe adjacent portion of the column of coarse coal over the wholeheightof the retort and willrapidly escape. upward through theinterstices and passages existing Within the column of coarse coal. I.thereby avoidthe danger of losing gas rnd -lso of` bulging the retort,such as might exisi if the gas were confinedin spaces from which esca ewas difficult.

he drawing illustrates an apparatus in which only two grades or sizes ofcoal are employed. It will be evident, however, that anybody skilledinthe art could modify the apparatus so that three or more grades of coalcould be used and transferred to the retort to form asmany layers orcolumns therein. It will yalso be understood that myjin; ventionmay beapplied in conjunction with retorts which are notvertical.

' I claim as my invention 1. In an .apparatus for charging retorts, thecombination of a receiver having separate chambers and separatedischarges for each of them, a ldistributing funnel arranged totransfer'the'coal from said receiver to the retort and provided withcompartments each of -v which corresponds with a/chamber of thereceiver, the outlets of both compartments beceiver having separatechambers, a funnel v .having compartments arranged to reg1ster With thechambers of theA receiver, the outlets of said compartments being adjacentlto the retort in the charging position and having an aggregateWidth not exceeding that of the retort, and means for controlling thedischarge from the receiver and from the funnel res e'ctively.

3. .-T e combination With the retort, of a plurality of chambers adaptedto containl fuel of different grades, compartments equal in number tosaid chambers and each arranged to receive materialv from one oi saidchambers, the outlets aid compartments being adjacent to eaciA and tothe receiving end of the the charging position, means-for co @lling thepassage of the material from chambers to said compartments, and meansfor controlling the discharge ct the material from said compartments.

4. The combination of the retort, the re-` ceiver having individualchambers with outlets located adjacent to each other, a funnel havingcompartments the upper ends of Which are in receiving relation to thesaid outlets of the receiver and the outlets of which are locatedadjacent to each other and close to the retort in the charging position,and means for controlling the discharge oi' material from the receiverand from the 'funnel respectively.

5. T e combination of stationary chambers adapted to contain material ofditierent grades and having their outlets adjacent to each other, adistributing funnel arranged to travel under said outlets and having anumber of compartments corresponding to said chambers, and means forcontrolling the discharge of material from the said chambers and fromthe funnel respectively.

6. The combination of the retort, afre-I ceiver having individualchambers and means whereby fuel will be distributed to said chambersaccording to its size, a funnel having compartments in receivingrelation to said chambers and outlets located adjacent to each other andto the inlet of the retort in the charging position, and means forcontrolling the outlets of the said chamber and funnel compartmentsrespectively.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
